Abstract
The invention provides a carbon fiber composite core rod and aims to solve the problems that a molded carbon fiber core rod is crisp and hard, has poor bendability, can only be wound on a circular disk tool with the diameter of 77D and is inconsistent with the international requirement. Key points of the invention are that: a plurality of strands of glass fibers are embedded into the outer surface of a carbon fiber round rod and along the axial direction of the round rod, namely each strand of glass fiber is parallel to the axis of the round rod; seen from the cross section of the round rod, the plurality of glass fibers are uniformly distributed on the circumference of the round rod; and the outer surface of the carbon fiber round rod into which the glass fibers are embedded is coated with glass fiber cloth. The carbon fiber composite core rod has the advantages that: the plurality of strands of glass fibers are embedded into the carbon fiber rod, so that the toughness and flexibility of the carbon fiber rod are enhanced remarkably and the carbon fiber rod is accordant with the international standard.
Description
Technical field
The present invention relates to a kind of plug of cable, is carbon fiber composite core rod specifically.
Background technology
The plug of traditional steel reinforced aluminium conductor (cable) is a rod iron, and steel core bar Heavy Weight, thermal coefficient of expansion are big, non-refractory, resistance to corrosion are poor, have restricted the defeated development that becomes industry.Numerous for this reason patent documentations disclose the scheme that replaces steel core bar with the carbon fiber plug.Advantage such as that the carbon fiber plug has is in light weight, thermal coefficient of expansion is little, high temperature resistant, good impact resistance, resistance to corrosion are strong is the steel core bar good substitute product.But national standard requires cable should be able to be wrapped on the circular discs tool that diameter is 55D at least one circle.Because the carbon fiber plug after the moulding is more crisp, harder, bendability is relatively poor, and generally it can only be wrapped on the circular discs tool that diameter is 77D, does not meet the requirement of above-mentioned GB.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of carbon fiber composite core rod.
Carbon fiber composite core rod provided by the invention is: it has the carbon fiber pole; It is characterized in that: at the outer surface of carbon fiber pole, axially inlay some strands of glass fibers (per share contain glass fiber 2400-4800 dawn) along pole; Be that per share glass fiber is parallel with the axle of pole; See that from the pole section some strands of glass fibers are evenly distributed on the circumference of pole, coat glass fabric at the outer surface of having inlayed the carbon fiber pole behind the glass fiber.More than some strand generally grasp between the 4-10 thigh.
The method of making carbon fiber composite core rod is:
1, carbon fiber and some strands of glass fibers are sent in the constant temperature hopper soaked into gluing;
2, use becomes rod through improved spreader with carbon fiber with some bursts of glass fiber pultrusions; Said being meant through improved spreader opened the glass fiber passage on the dividing sinker wall; The import of this passage is located on the wall near yarn inlet, the crowded excellent channel connection of outlet and spreader; The axis of glass fiber passage and the axis folder 15-25 degree angle of squeezing excellent passage; Several glass fiber passages are evenly distributed on the circumference of spreader outer wall; The number of share of stock of glass fiber equates with the number of glass fiber passage.Carbon fiber is sent into and is squeezed excellent passage, one glass fiber is sent into a glass fiber passage; Under the traction of the index machine of spreader postorder stretches; Spreader is extruded the carbon fiber rod of gluey band glass fiber, and even the carried interest glass fiber evenly is being embedded in the outer surface of carbon fiber rod along axial (with axially parallel);
3, coat glass fabric on the surface of the carbon fiber rod of being with glass fiber; To prevent that glass fiber is loose, to tear, go out burr; And be convenient to strand dress cable, and solved carbon fiber and these two kinds of fibre strength percentage elongations of glass fiber do not match, cause the problem of unbalance stress;
4, send into second yarn guide, remove unnecessary resin;
5, send in the preforming tool and be heating and curing, obtain the composite core of semi-solid preparation after, again the composite core of above-mentioned semi-solid preparation is sent into the back curing oven and carries out back cured, one-tenth the present invention.
Compare with existing carbon fiber plug; The invention has the beneficial effects as follows: owing on carbon fiber rod, inlayed some strands of glass fibers; Its toughness and flexibility are had significantly improve, National standard can be wrapped in the requirement of at least one circle on the circular discs tool that diameter is 55D about cable.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the axial section of the spreader after improving.
Embodiment
Referring to Fig. 1; At the outer surface of carbon fiber pole 3, axially inlay six strands of glass fibers 2 along pole; Be that per share glass fiber is parallel with the axle of pole; See that from the pole section six strands of glass fibers are evenly distributed on the circumference of pole, coat glass fabric 1 at the outer surface of having inlayed the carbon fiber pole behind the glass fiber.
The manufacturing approach of carbon fiber composite core rod is:
1, high-performance carbon fibre and high strength glass fiber are at the uniform velocity involved from creel, it is got in the moisture separator through collection yarn device remove moisture;
2, will go wet high-performance carbon fibre and high strength glass fiber to send in the constant temperature hopper and soak into gluing;
3, use becomes rod through improved spreader with carbon fiber with some bursts of glass fiber pultrusions; Saidly be meant that through improved spreader (referring to Fig. 2) opens glass fiber passage 5 on dividing sinker wall 4; The import of this passage is located on the wall near yarn inlet, and outlet is communicated with the crowded excellent passage 7 of spreader; The axis of glass fiber passage 5 presss from both sides 20 degree angles with the axis that squeezes excellent passage; The glass fiber passage is six, and they are evenly distributed on the circumference of spreader outer wall.Carbon fiber is sent into and is squeezed excellent passage yarn inlet 8, one glass fiber is sent into a glass fiber passage; Under the traction of the index machine of spreader postorder stretches; The carbon fiber rod of the band glass fiber of the glue of extruding from spreader outlet 6, promptly six strands of glass fibers evenly are being embedded in the outer surface of carbon fiber rod along axially (with axially parallel);
4, coat glass fabric on the surface of the carbon fiber rod of band glass fiber, preventing that glass fiber is loose, to tear, go out burr, and be convenient to strand dress cable, and solved carbon fiber and these two kinds of fibre strengths of glass fiber do not match, cause the problem of unbalance stress;
5, make the carbon fiber rod of gluey band glass fiber get into the unnecessary resin of removal in second yarn guide;
6, send in the preforming tool and be heating and curing, obtain the composite core of semi-solid preparation after, again the composite core of above-mentioned semi-solid preparation is sent into the back curing oven and carries out back cured, one-tenth the present invention.
